Mr Donald Trump's animus towards Fox News anchor Megyn Kelly dates to August last year, in the first presidential primary debate, when Ms Kelly, as moderator, questioned him about his past comments denigrating women.
Afterwards, he suggested that Ms Kelly had treated him "unfairly", and been so angry that she had blood pouring out of her "wherever" - a remark many saw as a reference to menstruation.
In the months since, Mr Trump, 69, has repeatedly criticised Ms Kelly as a "third-rate" reporter. And as today's debate approached, he began disparaging her as if he were a prizefighter promoting a rematch. He called her dishonest, accused her ofbias and conflict of interest, and said flat out he did not like her.
Ms Kelly, 45, who has a law degree and worked as a corporate litigator for nine years, joined Fox News in 2004, according to the network's website. News stories she has covered include the 2013 government shutdown, the Boston bombing and the Pope's election.
